Strips of grass bordering roads (6)
I believe the answer is:
verges
'strips of grass bordering roads' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for verges that I've seen before include "Roadsides" , "Strips of grass bordering roads" , "Limits, boundaries or borders" , "Grass borders on roads" , "Edges or thresholds" .)
